Former assassin David Slaton discovers a cryptic message: on a memory stick, a photograph of the man who will soon assume command of DGSI, France’s elite counterterrorism force. With the country reeling under a wave of ISIS attacks, Zavier Baland will be trusted to make the Republic safe again. The problem—Slaton has seen Baland’s face before. He is Ali Samir, a terrorist Slaton is certain he killed fifteen years earlier. Unable to reconcile these facts, he heads west to investigate.

Thousands of miles away, ISIS’s chief information officer tries to keep networks running amid crumbling infrastructure. With the caliphate’s very survival at stake, the leadership commits to a last-ditch gambit: France must be attacked on a massive scale, forcing the West into the battle of the Apocalypse.

Slaton keeps a breakneck pace, traveling from Tel Aviv to Paris and farther, each step uncovering both new threats and new opportunities. A small band of jihadists navigates the Baltic in a hijacked boat, steering toward a strike that will bring France to her knees. On the third side of a devil’s triangle, France’s incoming counterterrorism chief prepares a labyrinthine plot of his own. Only one man is in a position to stop the gathering storm.
